Wash. Rev. Code § 77.120.005
The legislature finds that some nonindigenous species have the potential to cause economic and environmental damage to the state and that current efforts to stop the introduction of nonindigenous species from shipping vessels do not adequately reduce the risk of new introductions into Washington waters.
The legislature recognizes the international ramifications and the rapidly changing dimensions of this issue, the lack of currently available treatment technologies, and the difficulty that any one state has in either legally or practically managing this issue. Recognizing the possible limits of state jurisdiction over international issues, the state declares its support for the international maritime organization and United States coast guard efforts, and the state intends to complement, to the extent its powers allow it, the United States coast guard's ballast water management program.
